FOSTER, AND THE AUTHOR PREFACE THE stories in this volume were written with the definite purpose of illustrating the great primal truth that wherever there is life there are problems confront- ing it; and that the way of solving these problems has been the way to success in the evolution of a species. The writer has hoped to depict also, in some measure, the dignity of life’s upward struggle, however humble the incarnation. No excuse is offered that the facts herein given were not ascertained through original and personal investi- gations; the object of the volume is not to give new facts, but rather to give another standpoint for viewing the facts already known. Yet the reason for selecting these particular stories out of a world full is that I have read chapters of them with mine own eyes, and - have been able here and there to add something not before recorded. The complete story of the Ceratina was brought to me page by page from the fields by my husband for my daily entertainment while I was pros- trated by a tedious illness. The Little Nomad was my special chum during a summer vacation. The Seine Maker is a water sprite that has lured me to various vii : vill PREFACE indiscreet excursions to the middle of swift streams. And the crickets, bees, wasps, and ants have been our boon companions for many a happy summer and autumn. “The Story we love Best” was published in the Saint Nicholas magazine in June, 1889. “The Perfect Socialism,” “ Pipers and Minnesingers,” and portions of “Two Mother Masons” and “A Sheep in Wolf’s Cloth- ing” were printed in different numbers of the Chautau- quan during the year 1898. “A Tactful Mother” and “A Dweller in Tents” were written for the young readers of the Observer in 1897, and “Hermit and Troubadour” appeared in the Cornell Nature-study Bulletin for June, 1899. I wish to acknowledge the courtesy of The Century Co., of Dr. Theodore L. Flood, of Dr. Edward F. Bige- low, and of the Cornell University Nature-study Bureau for cordial permission to reprint these several stories. I also wish to acknowledge the helpfulness of Mr. W. C. Baker and Mr. O. L. Foster in obtaining for me suitable illustrations. And I wish to express my thanks to Miss Mary C. Dickerson for the use of Figs. 21 and 26, and to Miss Mary E. King, whose direct assistance has enabled me to prepare this volume for publication at the present time. ANNA BOTSFORD COMSTOCK. Irnaca, N.Y., April, 1903. CONTENTS CHAPTER PAGE I.

Yet if the listener in the summer meadows or summer darkness be analytic, if his ear be attuned to the harmonies of nature, he will dis- cover that the air is filled with the soft music of a vast orchestra — music so continuous and so monoto- nous that it seems rather to belong to earth’s silences than to earth’s sounds. Few of us realize how oppressive would be utter silence; and few of us comprehend the debt of gratitude that we owe to 4 4 WAYS OF THE SIX-FOOTED the little fiddlers in the grass, the drummers in the trees, and the pipers in the air. There is cheer in their music, as well as restfulness. Their fugues afford companionship, and at the same time inspire in us a comfortable sense of isolation and peace. The subject of insect music should not be dealt with as a purely scientific study, for it has been closely connected with the poetry of the ages. A dis- cussion of these little musicians would be incomplete without reference to the impression they have made upon the poet mind, which ever reflects, intensified, the experiences of humanity. Among those poets who really take us into the fields some have paid tribute to our insect friends. But among the vast hordes of insects only a few have been chosen as fit subjects for song. These favored ones are butterflies, moths, flies, bees, fireflies, dragonflies, cicadas, grass- hoppers, crickets, katydids, and beetles. Of these twelve kinds of msects it will be noticed. seven are musicians, and are almost invariably mentioned in connection with the sounds they make, as “the buzzing fly,” “the droning bee.” All this proves that our literary people are better at listening than at seeing; for to the naturalist there are many other insects that press more deeply into the realm of poetry than do these. PIPERS AND MINNESINGERS 5 It is true that the great majority of our species of insects are silent. The few insects which make sounds do not have true voices. As insects do not breathe through their mouths, but through holes ar- ranged along each side of the body, they naturally possess no such arrangement for vocalization connected with breathing as we find in our larynx. The sounds made by insects may be divided into three classes: first, sounds emitted to frighten the foe; second, sounds made in connection with flight; and third, true love songs. The insects making sounds of the first sort are few; they make clicking or grating noises and clearly do not belong to the musical tribes. The buzzing and droning notes given off by insects when flying may be accidental or may be of some significance to the insects; we really know very little of the methods or reasons for these songs. . When we hear a certain buzzing we are just as sure that a fly has been caught in a spider’s web as we are after we see the remonstrating little victim. But, whether or not this noise is of any use to the fly, we do not know. Those of us who have had experience with bees know very well by their buzzing whether they are happy, distressed, or angry; we know, too, that they are well aware of each other’s emotions ; 6 WAYS OF THE SIX-FOOTED but whether they gain their intelligence through hearing different sounds, as we do, is a matter not yet settled. We know, however, that the piping of a young queen in her cell, just before a second swarm emerges, excites the whole colony greatly; thus we have evidence that bees are sensitive to at least one sound. The older naturalists made futile experiments to discover whether the sounds of the bees and flies were involuntary and caused simply by the vibrations of the air made by rapid motions of the wings; or if the note given off was caused by air expelled from the spiracles against the vibrating wings, on the same plan as the note of the jews-harp. Recent investigations seem to show that the vibration of the walls of the thorax, as well as the vibrations of the wings, cause the sound. As for myself, I prefer to believe that the mellow hum which pervades the air of midsummer afternoons is a voluntary hymn of praise for sunshine and blue skies. THe PrIrers The poets have not been generally complimentary to flies. Tennyson, in one of the most bitter stanzas of “ Maud,” says: — “Far off from the clamor of liars belied in the hubbub of lies * * * * * * PIPERS AND MINNESINGERS 7 Where each man walks with his head in a cloud of poisonous flies.” Shakespeare alludes to them several times in much the same spirit. Of all the members of the families of flies, the mosquito has received most personal attention from the poets; perhaps because she has been lavish in personal attentions to them. Bryant has deemed her worthy of a separate poem, in which he recognizes her as a fellow-singer : — “Thou’rt welcome to the town; but why come here To bleed a brother poet, gaunt like thee ? Alas, the little blood I have is dear, And thin will be the banquet drawn from me.” How much we might enjoy the song of the mosquito if it were not associated with the unwilling yielding of blood to the singer is problematical. Perhaps if Beethoven’s Pastoral Symphony were always to be played in our hearing when we were occupying the dentist’s chair, we would soon become averse to its exquisite harmonies. Therefore it is no wonder that we do not think of music at all when we hear the distant horn of the mosquito; instead, we listen with patient exasperation as the sound grows louder, and we wait nervously for the final sharp “ zzzzz”’ which announces that the audacious singer has selected a 8 WAYS OF THE SIX-FOOTED place upon us which she judges will be a good site for a pumping station. We do not like her noise a whit better even though it be a love song. The mosquito is an exception to all other msect min- nesingers, for she is the only one among them all that belongs to the female sex. The lover for whom she sings 1s a quiet, gentlemanly fellow who never troubles us, as he has no taste for biood; he may be found upon the window-panes, and may be recognized by his feathery antenne, which stand out in front of his head like a pair of pompons. The physicist, Professor A. M. Mayer, performed some interesting experi- ments which seem to prove beyond doubt that the antenna of the male mosquito are organs of hearing. Figure 2 shows one of these antenne. It will be noted ie. 2. that each segment bears a whorl of hairs Antenna of and that these whorls diminish in size Male Mosque toward the tip of the antenna. The experiment was as follows: Professor Mayer cemented a mosquito to a glass slide without injuring him, and observed him through a microscope while an assistant sounded tuning forks, varying in pitch, in different parts of the room. The note from a fork of low pitch caused the basal whorl of hairs to vibrate; a note from a higher key caused a whorl of hairs nearer the tip to PIPERS AND MINNESINGERS 9 vibrate. Thus Professor Mayer found that the range of one of these antenne extended over the middle and next higher octaves of a piano. From this it seems that this insect is equipped to enjoy the music of his lady; not only this, but, as was shown by further experiments, he is enabled to tell in what direction to find her. The large globular basal segment of the antenna has been found, on dissection, to be an audi- tory capsule. If poets have found little to enjoy in the buzzing of flies, they have been most appreciative of the other wing-singers, the bees; the allusions to their soothing strains are innumerable. The song of “The golden banded bees Droning o’er the flowery leas ” seems to have been comforting and dear to humanity for many centuries. The poetic literature devoted to bees is much larger than that given to any other insect, and at the same time more casual. They are constantly alluded to as companions of the flowers, and are, in the poet mind, an essential part of bloom- decked meadows and hillsides. Their peaceful hum is the background against which clover and fruit blooms are painted. “The blossomed apple tree, Among its flowery tufts, on every spray, 10 WAYS OF THE SIX-FOOTED Offers the wandering bee A fragrant chapel for his matin lay.” Thus Bryant finds the bee a ‘“‘ Fellow Worshipper.” The bumblebee has ever been a favorite with Amer- ican poets. Emerson has thought her worthy a separate poem, in which he pays this tribute to her music : — “Hot midsummer’s petted crone, Sweet to me thy drowsy tone Tells of countless sunny hours, Long days, and solid banks of flowers.” Tur MINNESINGERS To the minnesingers belong the insects which sing in order to facilitate their wooings. These are all of the masculine gender and are provided by nature with various sorts of instruments, upon which they play for the delectation of their ladies, who are mostly shy, silent creatures; however, they seem to have a very appreciative and, at the same time, a very dis- criminating taste for music. The first of the insect troubadours which we will study is the cicada. This musician is no near relative of the other love singers, as he belongs to another order of insects alto- gether. He is an interesting-looking fellow, with a stout body and broad, transparent wings quite ornately veined. Probably because of his song, his name has PIPERS AND MINNESINGERS 11 become confused with that of the locust, which is always a true grasshopper. The cicada whose song is the most familiar to us is the “ dog-day harvest-fly”” or “Lyreman” (Fig. 3). It resembles the seventeen-year species, except that it is larger and requires only two or three years in the immature state, be- low ground, instead of seven- teen. The Lyreman when seen from above is black, with dull-green scroll ornamentation; below he is covered with white powder. He lives in trees; hidden beneath the leaves, this arboreal wooer sends forth a high trill, which seems to steep the senses of the listener in the essence of summer noons. If you chance to find a Lyreman fallen from his perch and take him in your hand, he will sing and you can feel his body vibrate with the sound. But it will remain a mystery where the musical instrument is situated, for it is nowhere visible to the uninitiated. However, if you place him on his back, you may see directly behind the base of each hind leg a circular plate, nearly a quarter of an inch in diameter; beneath each of these Fic. 3. The Lyreman — an arboreal wooer. 12 WAYS OF THE SIX-FOOTED plates is a cavity across which is stretched a partition made up of three distinct kinds of membranes for the modulation of the tone; at the top of each cavity is a stiff, folded membrane which acts as a drumhead; but it is set In vibration by muscles instead of drumsticks, and these muscles move so rapidly that we cannot dis- tinguish the separate vibrations. Thus, our Lyreman is provided with a very complicated pair of kettledrums, which he plays with so much skill that his music sounds more like that of a mandolin than of a drum. The cicada was regarded as almost divine by the early Greeks. When Homer wished to compliment his best orators he compared them to cicadas. Anacreon, the most graceful of the lyric poets of Greece, addresses him thus : — “Sweet prophet of summer, loved of the Muses, Beloved of Phoebus who gave thee thy shrill song, Old age does not wear upon thee; Thou art earth-born, musical, impassive, without blood. Thou art almost a god.” The Greeks were so much attached to these insects that they kept them in cages for the sake of their songs; they wore images of them in their hair. The song of the cicada was the name given to the sound of the harp; a cicada upon a harp was the emblem of the science of music. We all know the beautiful story of PIPERS AND MINNESINGERS 13 the rival musicians, Eunomus and Ariston, and how during a contest in harp-playing a cicada flew to the instrument of Eunomus, took the place of a broken string, and thus won for him the victory. The ancients also seem to have known something of the habits of these insects, for the cynical Xenarchus tells us : — “ Happy the cicadas’ lives Since they all have voiceless wives.” Virgil also pays tribute to the cicadas thus : — “Et cantu querulae rumpent arbusta Cicadae.” The English poets have also paid the cicadas some attention. Byron, who seldom mentions the smaller things in nature, writes : — “ The shrill cicadas, people of the pine, Make their summer lives one ceaseless song.” The most graphic description of the song of our own cicada is given by Elizabeth Akers in the lines : — “The shy cicada, whose noon voice rings So piercing shrill that it almost stings The sense of hearing.” James Whitcomb Riley also characterizes him in his own vivid way in the poem on “ The Beetle * : — “ The shrilling locust slowly sheathes His dagger voice and creeps away Beneath the brooding leaves, where breathes The zephyr of the dying day.” 14 WAYS OF THE SIX-FOOTED Surely a new interest attaches to this summer-day song when we realize that it has pleased the human ear since the dim age of Homer. The cicada’s kettledrums are perhaps the only musical instruments now in use that have remained unchanged through a thousand centuries since they were first mentioned. The other of the insect love singers belong to the order Orthoptera and are quite closely related to each other. First among these are short-horned grass- hoppers, although they are not so musical as some of the other species. However, we find in this group ~ some veritable fiddlers. The long hind leg which is roughened with short spines is used as a fiddle bow, and is drawn across the wing cover, which acts the part of the fiddle, and gives off certain notes. These are our common grasshoppers and may be watched while fid- dling if one has the patience and wariness. These insects have found many admirers among the poets. Leigh Hunt apostrophizes the grasshopper thus : — “Green little vaulter in the sunny grass Catching your heart up at the feel of June, Sole voice that’s heard amid the lazy noon.” And Keats writes thus: — “ The poetry of earth is never dead; When all the birds are faint with the hot sun, And hide in cooling trees, a voice will run PIPERS AND MINNESINGERS 15 From hedge to hedge about the new-mown mead; That is the grasshopper’s. He takes the lead In summer luxury.” As may be inferred from these allusions these grass- hoppers sing during the heat of the day. Other species of this same group of grasshoppers make their music by rubbing the front surface of the hind wings against the under surface of the wing covers. This can only be accomplished when the insect is flying. The note is a crackling sound; how- ever, it is no accidental noise; it is as true a song as any, as I am sure all observers will agree who have seen one of these great, brown, roadside grasshoppers fly up into the air and hold himself there poised for minutes while he performs in apparent ecstasy his rapid, monotonous pizzicato. James Whitcomb Riley has seen him, as the following lines prove : — “ Where the dusty highway leads, High above the wayside weeds They sowed the air with butterflies, like blooming flower seeds, Till the dull grasshopper sprung Half a man’s height up; and hung Tranced in the heat with whirring wings and sung and sung and sung.” This description is so accurate that it actually identifies the species. Mr. Riley is the prince among 16 WAYS OF THE SIX-FOOTED poets that have sung Nature’s melodies in America. His sensitiveness to all out-of-door life, and his keen eyes, unto which not only the poetry but the truth of the fields and woods are revealed, make him a special delight to naturalists. They have to make no mental reservations when reading his poems. Elizabeth Akers was another satisfactory naturalist poet, and she too has noted this roadside grasshopper. She says :— “ The flying grasshopper clacked his wings Like castanets gayly beating.” Correlated with love singing must also be love listen- ing. While many insects have the chordotonal or true hearing organs inside the body, only a few have these connected with what we would, at first sight, call ears ; and it is interesting to note the odd places in which these ears are situated. The grasshoppers which have been described have their ears placed on each side of the body on the segment behind the one to which the hind legs are attached. These little ears may be seen with the naked eye if the insect’s wings be lifted out of the way; in appearance they are nearly circular disks. The first thought is, “‘Of course, since these ears were developed to hear love songs, they would naturally be nearer the heart than our own.” Unfortunately for this theory an insect’s anatomy is not arranged like PIPERS AND MINNESINGERS 17 ours. The insect heart is a tube that extends along the back, like our backbone, and it is a most disconcerting organ when regarded as a possible locality for senti- ment. The long-horned or mead- ow grasshoppers are usually bright green or pale brown in color and occur in the taller grass of the meadows. They have long antenne, as delicate as fine silken threads, which they keep constantly in motion (Fig. 4). These musicians have an apparatus for singing quite different from that of their short- horned cousins. The wing- covers, near their bases at Fic. 4. Meadow Grasshopper. the middle of the back, have a seria enlarged and sustained by strong veins (Fig. 5). One of these veins is ridged, and when drawn across the edge of the other wing-cover causes a vibration. The note given off is high but soft and pleasing; we associate it with the meadows in haying time and the heat of the day; however, several of our common species sing in the 18 WAYS OF THE SIX-FOOTED evening exclusively. One species of these grasshoppers lives in trees. The meadow grasshoppers have their ears in the same place as do the katydids (Fig. 9). Fic. 5. Wing-cover of Male Meadow Fic. 6. Wing-cover of Female Grasshopper. Showing Musical Meadow Grasshopper. Not a Organ. Musical Instrument. Another singer of love songs is the katydid. “T love to hear thine earnest voice Wherever thou art hid, Thou testy little dogmatist, Thou pretty katydid. Thou mindest me of gentle folks, Old gentle folks are they, Thou say’st an undisputed thing In such a solemn way.” I think this musician must have been some distance from Dr. Holmes when he wrote these lines; for dis- tance is needful to lend enchantment to the katydid’s song. The grating emphasis of the assertion “ Ka’-ty did’, she did’,” is nerve-lacerating when the listener is in close proximity to this bass viol of the insect orches- tra. Mr. Riley describes the song well when he says : — “The katydid is rasping at The silence from the tangled broom.” PIPERS AND MINNESINGERS 19 The word “‘rasping”’ is peculiarly felicitous in this description ; Elizabeth Akers used it also: — “The katydid with its rasping dry Made forever the same reply, Which laughing voices would still deny.” The katydids are near relatives to the meadow grass- hoppers; they live in trees and sing only in the even- ing and night. Despite his heavy voice the katydid is Fic. 7. Katydid. a very shy insect ; the only sure way to find him is to take a lantern and, guided by the sound, discover his retreat while his attention is distracted by his quite dis- tracting song. When found he is well worth looking at ; he is dressed in pea-green ; his wing-covers are so leaf- like in form and color that it is no wonder he is invisible when perched among the leaves. His face wears a very solemn expression, but somewhere in it is a suggestion of drollery, as if he could appreciate a joke; he keeps his long silken antenne waving in an inquiring way 20 WAYS OF THE SIX-FOOTED that suggests curiosity rather than fear. Figure 7 is” a picture of our common katydid; it shows the front triangular portion of the wing, — f L which is the instrument with i m which the katydid plays. Figure 8 shows the details of the triangular bases of the upper wings from be- Fig.8, Musteal Inswument neath; 7 is the left wing triangle of the Katydid. 7 . : and ris that of the right wing; the left triangle bears the file (f/f) and the right triangle bears the scraper (s); m the central portion of each triangle is a translucent membrane (#2), which is set into vibration when the scraper is drawn across the file and transmits the movement to the entire wing. The file is so large that it can be seen plainly with the naked eye. The song is so exactly like our own enun- ciation of the words “Katy did, Katy did, she did,” that the singer seems almost uncanny, and attracts universal attention wherever he. abounds. Of the insect musicians the cricket is easily the most popular. Long associated with man, as a companion of the hearth Fic. 9. Ear of and the field, his song touches ever the een chords of human experience. Although we, in America, do not have the house-cricket which English poets PIPERS AND MINNESINGERS 21 praise, yet our field-crickets have a liking for warm corners, and will, if encouraged, take up their abode among our hearthstones. The greatest tribute to the music of the cricket is the wide range of human emotion which it expresses. “As merry as a cricket” is a very old saying and is evidence that the cricket’s fiddling has ever chimed with the gay moods of dancers and merrymakers. Again, the cricket’s song is made an emblem of peace; and again we hear that the cricket’s “ plaintive cry”’ is taken as the harbinger of the sere and dying year. From happiness to utter loneliness is the gamut covered by this sympathetic song. Leigh Hunt found him glad and thus addresses him : — “And you, warm little housekeeper who class With those who think the candles come too soon, Loving the fire, and with your tricksome tune Nick the glad, silent moments as they pass.” The chirp of the cricket is, in literature, usually associated with the coming of autumn; but the careful listener may hear him in the early summer, although his song is not so insistent as later in the season. To me it is the most enticing of all the insect strains; there seems to be in it an invitation to “come and be cosy and happy while the summer and the sunshine last.” I have also always been an admirer of the manly and self- 22 WAYS OF THE SIX-FOOTED respecting methods of this little troubadour. He does not wander abroad to seek his lady-love, but stands sturdily at his own gate and plays his fiddle lustily, always doing his best ; he knows the shy lady is not far away, and that if she likes his song she will come to him when her heart is won. It is very easy to see the cricket making his “ crink,” as our British cousins call his cry. If you are careful, you may observe him in his own doorway; or perhaps an easier method is to catch several and place them in a glass jar in which there is a little sod; they will soon begin chirping in such a cage and may be watched at leisure. ; Each wing-cover of the male cricket is divided into membranous, disklike spaces on top (Fig. 10), and across each extends a vein covered with transverse ridges, the “file” (f/f); on the inner edge, near the base, is a hardened portion called the “scraper” (s). When chirping the cricket lifts his wing-covers and draws the scraper of one across the file of the other, “ and thus sets both im vibration. In order Fic. 10.

While the earlier songs of the Fie. 11. When the Afternoon Shadows in the Orchard lengthen. 24 WAYS OF THE SIX-FOOTED cricket are for wooing, I have come to believe that the later songs of the autumn are made for the love of music. Possibly he still plays on for the delectation of his mate, although the time of youth and love have passed by. At all events, after the mating season is gone, you may hear these indefatigable serenaders from the hour when the afternoon shadows in the orchard lengthen until late at night, playing as steadily as if they thought music the most important of occupations. The cricket ear is placed most conven- Fic. 12. Ear jently in the tibia of the front leg, so that of Cricket. . - ‘ these insects literally hear with their elbows. Figure 12 shows the ear of a cricket. The katydids and meadow grasshoppers have their ears placed similarly. The last but by no means least of our minnesingers is the snowy tree-cricket, the brave little musician of frosty autumn. You will hear him first as you stroll along some country highway that leads past woods and orchard, and loses itself over dreamy hills set in the amethyst haze of September afternoons.!' His music is so much a part of the landscape that you have perhaps never noticed it at all, and certainly you have never seen this shy fiddler. He lives mostly on trees and shrubs and is seldom visible because of his pallid green 1 See Frontispiece. PIPERS AND MINNESINGERS 25 color, which makes him seem a ghost of an insect rather than a real one. Figure 13 shows a male of the species ; his fiddle is in structure similar to that of the black cricket. He is a true ventriloquist, and it is almost impossible to find him by following the seeming direction of his song. There are two species of snowy tree-crickets common in eastern United States which resemble each other so closely in appearance that only an entomologist’s trained eye can distinguish them. However, their music is totally different. I remember well a certain September when I was as- sociated with two ento- mologists who spent most of their leisure in a patient and loving study of the habits of these two species. One they named “the whistler” and the other “ the fiddler.” The whistler is oftener found on low shrubs or in the grass, and he gives a clear, soft, prolonged, unbroken note. The fiddler’s note is louder and short and con- tinuously repeated. To the listener it soon seems like a refined and gentle imitation of the katydid’s song. There seem to be three notes, the first and third being Fic. 18. Snowy Tree-cricket. 26 WAYS OF THE SIX-FOOTED accented, “ Ka’-ty did’.” But when studied more closely we are not sure whether the accent is in the music or in the listener’s imagination; and, finally, in bewilderment we simply accept the fact that somehow there is a delightful rhythm in it and cease trying to analyze it. We also note that this singer’s vivacity is dependent upon warm temperature. So far as we know, this snowy tree-cricket is the only one of the insect musicians that seems conscious of the fact that he belongs to an orchestra. If you listen on a September evening, you will hear the first player begin; soon another will join, but not in har- ’ mony at first. For some time there may be a see-saw of accented and unaccented notes; but after a while the two will be in unison; perhaps not, however, until many more players have joined the concert. When the rhythmical beat is once established it is im as perfect time as if governed by the baton of a Damrosch or a Thomas. The “throbbing of the cricket heart of September” it has been fitly named. Sometimes an injudicious player joins the chorus at the wrong beat, but he soon discovers his error and rectifies it. Sometimes, also, late at night, one part of the orchestra in an orchard gets out of time with the majority, and discord may continue for some moments, as if the players were too cold and too sleepy to pay good attention. This PIPERS’ AND MINNESINGERS 27 delectable concert begins usually in the late after- noon and continues without ceasing until just before dawn the next morning. Many times I have heard the close of the concert; with the “wee sma’ hours the rhythmic beat becomes slower ; toward dawn there is a falling off in the number of players; the beat is still slower, and the notes are hoarse, as if the fiddlers were tired and cold; finally, when only two or three are left, the music stops abruptly. Fitly and fortunately the song of this cricket is the most soothing of all the songs of insects. To listen to it consciously would make the most unfortunate victim of insomnia drowsy. It is the incarnation in sound of the spirit of slumber ; it broods over the care-tired world, and with gentle insistence hushes it to sleep. A Restful, Woodsy Path. Fic, 14. II A LITTLE NOMAD NE warm August morning I followed a certain restful, woodsy path which soon Mm, led me to a partially wooded hillside. ~~ I found a shady resting-place under a pair of twin maple trees, where I settled contentedly in the grass with some downy young sumacs for neighbors. The blue waters of the lake twin- kled up at me through the tree-boles, and a blue sky beamed down on me through the tree-tops. The breeze, playing softly with the leaves above me, and the soft swish of the water on the rocks below united in a sooth- ing song, to which a cicada from his high perch was doing his best to perform a worthy obligato. I was tired of a world of work and care; and as I turned my footsteps toward this cosy nook I said to myself, “I will go where I can be alone.” Vain decision and absurd desire! I had just arranged for myself a tree-trunk chair-back and was enjoying the nice bark upholstery when a grandfather graybeard came teetering along on his stilts, letting his body down at rhythmic intervals to 29 30 WAYS OF THE SIX-FOOTED feel of my hand with his palpi to discover if perchance I were good to eat. Then a red squirrel darted up a young ash tree in front of me, the dark stripe on his side where the red and white meet being particularly vivid and dashing ; at first he sneezed and coughed his displeasure at my intrusion and then sprang his rattle so suddenly that I wondered if it might be that squir- rels have secreted in them storage batteries that may be switched at will from action to sound. Then a great butterfly, a tiger swallowtail, came careening down through a hole in my leaf canopy and alighted on a sunlit bush near me; there, in utter luxuriousness, he slowly opened and shut his wings in obvious enjoyment of his sun-bath. While watching him I noticed that the maple sapling, on which he was resting, was in a bad way; its leaves were riddled with holes, varying in size from that of a bird shot to that of a small _ bean. Now while I was tired of a world that lectured and talked and argued and did many other noisy things that wore on one’s nerves, I was by no means tired of the great silent world that did things and made no fuss about doing them. So, when my butterfly drifted away, I lazily began to investigate the cause of the dilapidation of the maple leaves. There I found, as I suspected at first glance, a little nomad Fic. 15. Twin Maples. 32 WAYS OF THE SIX-FOOTED named the Maple-leaf Cutter, which pitches its tent on leafy plains and whose acquaintance I had made Fic. 16. Maple-leaf Cutter: Moth and Camping-ground of Caterpillar. several years ago when I was employed to make its family portraits. I plucked a leaf that had several oval holes in it and A LITTLE NOMAD 33 also several oval rings marked by a tracing of bare veins and translucent leaf tissue (Fig. 16); then I noticed an oval bit of leaf wrong side up on the upper surface of the leaf. A glance at this through my lens showed that it was made fast to its place by several bundles of glistening white silk. With a knife point I tore asunder these ropes and lifted the wee tent and found fastened to its under surface another bit of the leaf identical in shape but somewhat smaller. Suddenly from an opening be- tween the two an inquiring head was thrust out with an air that said plainly, “Who’s there?” I tore the two pieces of leaf apart to get a better view of the little imate. He was a stocky, brownish caterpillar, about one-sixth of an inch Fie.17. Caterpil- long, with shields on his thoracic seg- rot Maple-leat Cutter enlarged. ments that shone like polished bronze and an anal shield that was dull purple (Fig. 17). His several simple eyes were in two such compact groups that they gave the impression of two keen, beady, black eyes, and I had a feeling that he was inspecting me through the lens. He was very unhappy and squirmy when removed from his cover, and he backed so vigorously that he backed half his length out of the rear end of his tent before he 34 WAYS OF THE SIX-FOOTED felt safe, and then remained very still. His loosened tent was lying bottom side up on the leaf; and owing to my clumsy proportions I was obliged to leave the labor of righting it to him; he gave it his immediate attention and went at it in a most workmanlike manner. He crawled halfway out upon the leaf and by a dexterous lift of the rear end of his body he brought the tent down right side up and at once began pegging it down. To do this he moved his lower lip around and around on the leaf surface to make fast, then spun his rope up and lifting his head fastened it to the edge of the tent ; this process he repeated many times, but with great rapidity, and when the fastening was finished it was well worth seeing. He had spun his silken cords so they formed an X. This arrangement allowed him room to fasten many lines to the leaf and tent, and since they were crossed in the middle they had the strength of many twisted strands (Fig. 18). He put his first fastening at one side of his tent and then hastened to put another on the opposite side, and thus made secure he took his time for putting down the remainder of his ropes. Fic. 18. Tent Ropes of / the Maple-leaf Cutter. A LITTLE NOMAD 35 While watching him spin, I mused on his history as revealed in its earlier chapters by that truly great scientist, Dr. Fitch, and added to in its later chapters by our own Dr. Lintner, — two men of whom New York is so justly proud. This history was as follows: Last May a tiny moth (Incurvaria acerifoliella) sought out this maple sapling; she was a beautiful little creature with a wing expanse of a little more than a half inch; her front wings and thorax were steel-blue, and her hind wings and abdomen were pale, smoky brown ; these hind wings were bordered with a wide, fine fringe ; across both sets of wings glinted and gleamed a purple iridescence like that on the surface of a bit of mother-of-pearl. On her head, between her antenne, she wore a little cap of orange feathers, this color com- bination of orange and steel-blue proving her to be a moth of fine discrimination in the matter of dress. This pretty mother moth laid an egg upon the leaf which I held in my hand; from that egg hatched my wee caterpillar, and began life, I suspect, as a true leaf- miner. However, this is a guess of my own, inspired by the appearance of the leaf. Anyway, he did not remain a miner long, but soon cut out a bit of the leaf and pulled it over him and pegged it down; beneath it he pastured on the green leaf-tissues in safety, and in this retreat he shed his skin. With added growth came 36 WAYS OF THE SIX-FOOTED the need for more commodious quarters; so he cut ‘ another oval piece from the leaf, as much larger than his tent as he could reach without coming entirely out of his cover; before he cut it completely free he mgen- iously fastened one side of it to the leaf with silk so that he would not fall, cradle and all, to the ground. He then used this fastening as a hinge as he came part way out of his tent, took a good hold of the leaf with his sharp claws, and flipped the loosened piece over his back and fastened it down over fresh feed- ing-eround. What was previously his tent was then a rug beneath him ; his new pasture was a margin of about one-twelfth inch that lay between the edges of his rug and his tent; for he was ever averse to exposing his pre- cious person to lurking enemies more than was strictly necessary. Before Fic 19. A Lilliputian he shed his skin again he may have Mud-turtle. : needed a new pasture; if so, he struck his tent and walked off with it on his back, looking like a Lilliputian mud-turtle, and finally fastened it on a new site (Fig. 19). He had already several times gone through this process of upsetting his house, for he had two rugs beneath him and two tents above him of graduated sizes. And I knew that some time in the near future he would A LITTLE NOMAD 37 peg down his largest tent more securely than he had ever done before, and there in this safe shelter would change to a pupa. When the leaf that had been the range of this small nomad fell in the autumn he would go with it; and wrapped in his tent rugs he would sleep his winter sleep under the snow until he should awaken next spring, no longer a tenter on leafy plains, but a true child of the air. I tore off a bit of the leaf on which my little friend had settled, and went over and pinned it to a leaf still on the bush. It may have been an absurd thing to do, but by this time I was shamelessly, nay, intrepidly sentimental, and I did not wish that little chap to starve because of my inborn tendency to meddle with other people’s affairs. I then fell from bad to worse and began to moralize; for when a naturalist falls to moralizing science weeps. I meditated thus, “I came here to get away from puzzling problems, and yet here they are all around me; the problems of the little nomad; the problems of the poor, leaf-lacerated maple ; and if I look in other directions I will find more in plenty.” But for some sweet reason I did not feel about problems as I did when I ran away and hid from the noisy world two hours before. I was filled with a new sense of the dignity and grandeur of this great silent struggle for adjustment and supremacy which 38 WAYS OF THE SIX-FOOTED was going on around me. I felt inspired to go back and serenely do my own little part as well as I could, trusting that somehow, somewhere, and _ to Some One the net proceeds of struggle are greater than _ the cost. Ill A SHEEP IN WOLF’S CLOTHING O hatch from the egg, to attain growth through steady attention to eating, to reach maturity and produce eggs for another generation, are the necessities of insect life. The ways and means of accomplishing these things success- fully is a problem which is partially solved by the habits of the species, and partially by the efforts of the individual. The habits of a species comprise the wisdom stored up in the experience of that species during thousands of years; the habits of a species is the pathway by which it has struggled up to the ranks of the “ fittest > which have survived. No insect history better epitomizes the history of a race than does that of the Viceroy Butterfly (Lasilar- chia archippus), a beautiful insect which in early sum- mer makes our open fields and marshy meadows brilliant with the flashing of orange-red wings in the sunshine. The early stages of the Viceroy have been worked out in detail and given to the world through the careful and patient labors of Dr. 8S. H. Scudder. 39 Fie. 20. The Home of the Young Viceroy. A SHEEP IN WOLF’S CLOTHING 41 The Viceroy mother selects usually the terminal twigs of some willow or poplar, and places her eggs singly on the tips of the terminal leaves (Fig. 20). Now this choice of the topmost leaf of the branch is not without reason on the part of the mother. This egg, though scarcely so large as a pinhead has many enemies ; there are spiders always prowling around to find tidbits for their rapacious stomachs; there are tiny ichneumon- flies ready to lay their eggs within even so small an ege as this; there are wasps and other voracious insects always on the lookout for things eatable. So there is reason for putting these eggs one in a place on the tip end of a branch, where the wind always keeps the leaves stirring in a way to confuse the vision of these active foes. As a protection against these same inquisitive eyes the ege is of a dark green color, almost the exact hue of the upper surface of the leaf on which it is invari- ably placed. This little green egg is a beautiful object when viewed through a microscope ; it is ornately sculp- tured in an hexagonal pattern and set with short spines. It seems to be one of nature’s laws of beauty that noth- ing is too small to be worth while. After from four to eight days have elapsed since the ~ egg was laid, a little brownish larva gnaws its way out through the side. As soon as it is fairly out it turns around and eats the egg-shell, carving, spines, and all. 42 WAYS OF THE SIX-FOOTED Not for sentiment nor yet for digestion does the larva perform this somewhat auto-cannibalistic feat ; but for the very practical reason that the empty shell if left Fig. 21. Viceroy Caterpillar on Bare Midrib behind Decoy Bundle at A ; B, Winter Home of Viceroy Caterpillar. would mayhap yield a clew to his enemies which they might follow up to his undoing. Then the little cater- pillar begins feeding across the end of his native leaf, leaving the midrib untouched. Maybe the midrib is too A SHEEP IN WOLF’S CLOTHING 43 tough for the jaws of a baby caterpillar. On the other hand, his subsequent actions would seem to imply method in his manner of attacking the leaf; for the Viceroy larva is a night feeder, and he uses the denuded midrib as a perch during the day. Stretched out lengthwise on this he is nearly invisible during his earlier stages. Besides this, he uses a very ingenious device to distract the attention of keen eyes from his precious person ; he fastens with a silken thread a little bunch of débris to the bare stem between his feeding- place and his resting-place (Fig. 21). This is a clever performance ; for if one of his foes should be hunting on this leaf and should start out on the denuded stem it would meet with this empty and worthless mass and would naturally be discouraged from further investiga- tion. As the caterpillar gnaws off more of the leaf he moves his ambush bundle farther down the stem; so it is evidently of some real use to him. After a few days our caterpillar finds his skin too small for his increasing size and proceeds to shed it caterpillar-wise ; but he is still unwilling to leave any traces of himself around, so he eats up his old skin as he did his egg-shell. He soon destroys the leaf of his birth and then consumes others. In the course of his growth he sheds his skin three times and after each moult he assumes a change of form and color. Various 44 WAYS OF THE SIX-FOOTED warts and tubercles appear on him after the first moult ; these grow more numerous and noticeable with each succeeding change until he becomes a most grotesque and amazing-appearing creature, with a pair of spiny pompons in front and spines too numerous to mention decorating his body. Most people not entomologically educated would exclaim on seeing this caterpillar when full grown “ The horrid thing!” And if the caterpillar could hear and be conscious of the history of his race as embodied in himself, he would rejoice and be exceed- ing glad over this verdict ; for it is greatly to his advantage now to look so disagreeable Fie. 22. “So humpy and spiny that no one would willingly that no bird would touch him.”’ molest ha. ‘The height at his racial ambition is to be so humpy and spiny that no bird, however rash, would dare to touch him. His coloring now is pale olive, with a large white blotch in the middle so as to make him resemble a bit of bird-lime on a leaf. Not only in color and shape is he ugly, but he seeks to intimidate by his movements any approaching enemy. When he walks his head trembles as if he had the palsy, making the whole leaf quake and likewise the heart of the foe. If he is attacked or disturbed, he will fly into a tremendous rage and swing his head from one side to A SHEEP IN WOLF’S CLOTHING 45 the other in a ferocious fashion. Myr. Scudder saw two of these caterpillars meet, and each began a great swinging of the head, hitting the other several times durmg this family jar. When fully grown the cater- pillar, if disturbed, moves his head around in a circle on the leaf and “ genashes his teeth” in fury. To one who understands him this is a very funny bluff; for he is not only absolutely harmless, but he is also very fastid- ious about his food and could not be in- duced to take a bite out of an assailant. When the Viceroy changes to a chrysa- lis he is almost as grotesque in form as when he was a larva; for he now wears a large excrescence in front that bears a resemblance to a Roman nose (Fig. 23). The obvious use of this protuberance is to convince a bird of the utter futility of attempting to swallow such an uneven morsel. _ About a month after the egg is laid the adult isect appears, and on gorgeous wings sails off to join its fellows; for this is a social butterfly and is fond of dancing about in the air with its comrades. Very soon are the eggs laid for another brood. But the history of an individual of this generation is very different in some particulars than the one just related. After a larva of the second brood hatches, he feeds, as Fie. 28, ‘+ An un- even morsel.”’ 46 WAYS OF THE SIX-FOOTED did his parent, on the tip of the leaf, leaving the mid- rib for a perch during the day. But when he is about one-third grown he commences to display a peculiar interest in a certain, chosen leaf. He first fastens the petiole to the branch by weaving around the two many strands of silk; this is to keep the leaf from falling when assailed by the fierce winds of autumn. He then proceeds to the tip of the leaf and gnaws it off squarely across, leaving the midrib bare as usual; he is a clever engineer and leaves just enough of the leaf to suit his purpose. He folds the remaining por- tion of the leaf into a tube and sews it with a neat silken seam and then lines the tube luxuriously with silk (Fig. 21, B). The little house thus made is just large enough for the insect’s body; and he crawls into it, his warty last segment fitting nicely the orifice and constituting a living door. The question at once suggests itself, how does this larva know how to do this thing? His parents did not do it, and if he inherited the knowledge it must have been from his grandparents. This is one of the inscrutable mysteries ; and all we know about it is that during the warm days of autumn, long before there is any hint of winter in even the skies, this caterpillar, which never experienced a winter and whose parents never experienced a winter, builds himself this winter house and hides himself A SHEEP IN WOLFS CLOTHING 47 within it. Moreover, he selects a leaf near the ground so that he may have the protection of a cover of snow, which proves him to be truly winter-wise. He and all his generation pass the winter safely in their tiny tene- ments, remaining there dormant until the first buds or catkins of the spring call them to a vernal break- Fig. 24, The Viceroy. fast ; then they back out of their dwellings and devote themselves thereafter to eating and growing as if they had never experienced a winter vacation while pursu- ing this important business. They change to butterflies in June. The flight of the Viceroys consists of a few rapid flutters of the wings and then a period of sailing through the air with wings extended. This exposes them mercilessly to the attack of birds which regard 48 WAYS OF THE SIX-FOOTED most butterflies as the most delectable sort of food. This butterfly is especially agreeable as a diet to birds, and yet they rarely touch it. Why is this? It is another instance of the marvellous adaptation of this species to its environment, and of its power to seize an advantage in a precarious situation. This wonder- Fic. 25. The Monarch. ful little creature that resembled disagreeable things when it was young to save itself from being eaten by birds, now, when grown, resembles in color and mark- ings a butterfly which birds avoid for good reason. This butterfly (Anosia plexippus) is named the Monarch, and it belongs to a group all members of which are nauseous to birds. Its gay color, orange-red marked A SHEEP IN WOLF’S CLOTHING 49 with black borders and veins, is its protection; for it is an advertisement, a sort of a poster which proclaims that here is something that right-minded birds leave alone. So our palatable Viceroy has developed colors and markings so nearly like the unpalatable Monarch that no feathered creature will touch him, unless per- chance one shall be knowing enough to notice the black band across the Viceroy’s hind wings which is his chief distinguishing mark. To understand the magnitude of the feat accom- plished by the Viceroys in abjuring their family colors of black, white, and blue, and adopting the orange and black uniform of the Monarchs we must consider the vast differences in the earlier stages of the two species. The Monarch egg is laid upon the tender terminal leaves of milkweed and is quite as ornate as that of the Viceroy but of quite different pattern. When the caterpillar hatches, it pursues the same tactics as does that of the Viceroy; and for the same wise’ precaution eats its egg-shell. The milkweed is a succulent food, and the caterpillar may mature in eleven days; when full grown it is a gay creature banded crosswise with black, yellow, and green; on the second segment of the thorax and the seventh segment of the abdomen are a pair of black, flexible, whiplike filaments. They are smug-looking caterpillars, and they are smug in spirit 50 WAYS OF THE SIX-FOOTED also, for they are permeated with a race consciousness that the more they flaunt their gay stripes to the world the less likely are they to be attacked by a prudent bird. It is a great advantage to an insect to have the bird Fig. 26. ‘‘Smug-looking caterpillars. ”’ problem elimi- nated from the start. However, there remains the problem of para- sites and, there- fore, the black whips. When I was a child I dis- turbed a flock of these caterpillars resting together on the lower side of a leaf of wmilk- weed, and I still re- member the creepy fascination with which I gazed at the black and yellow ringed creatures and the waving, jerking-whips lashing back and forth to frighten away ichneumons; if the real ichneumons were as frightened as I was, the caterpillars were surely safe. A SHEEP IN WOLF’S CLOTHING 51 The chrysalis of the Monarch is the most beautiful gem in nature’s casket of living jewels. Its color is the most exquisite green, and it is enamelled with dots of shining gold; a gold far more wonderful than was ever mined by man. This ornamentation can be of no real use to the insect, and one is driven again to the conclusion that nature has so wrought this living jewel for the sake of beauty alone. From this emerald case comes, in due time, the great red-winged butterfly; and how so large a butter- fly can be packed in so small a case is nothing less than a miracle. If, perchance, the issuing butterfly is a male, then we have before us the veriest of insect dandies ; he is not only trig in figure and gorgeous in color but on each hind wing he carries a sachet bag embroidered in black. He indulges in no vulgar flirt- ing of a scented handkerchief to allure his lady-love; he simply flirts a beauteous red wing with a perfume pocket on it, and lo! she is won. But the Monarchs have other problems of their own just because the bird problem is eliminated. For because of this immunity they spread and flourished in their native tropic America until there came the problem of more food plants, more milkweed. And thus they began pushing farther north and south during the seasons of milkweed growth. As they 52 WAYS OF THE SIX-FOOTED could not endure the northern winter they simply came north for the summer and went back for the winter. At least this is what the wise men tell us. But this northern migration is carried on in a most peculiar manner. ach mother butterfly follows the spring northward as it advances as far as she finds the milkweed sprouted. There she deposits her eggs, from which hatch individuals that carry on the journey and lay their eggs as far to the north as possible; per- chance it is their children that we hear of in late sum- mer on the shores of Hudson Bay. As cool weather approaches the Monarchs gather in vast flocks for the southward migration. These flocks are not made up of the individuals that migrated north but of their chil- dren and grandchildren. There are no old ones among them travel-wise to guide them back to Florida and the West Indies. How they know the way is beyond our imagination, unless, perhaps, there flows in their bodies tropical blood that impels them to go back where the bamboo shades the stream, and the torn ban- ners of the banana wave on sluggish breeze. All we know is this: the Monarchs migrate northward by generations and southward by individuals; and from Patagonia to Athabasca swings the migratory pendulum. Nor is it content with this range; the strongest flier of all the butterflies it hesitates not to try its for- A SHEEP IN WOLF’S CLOTHING 53 tune over seas, and has been found flying bravely five hundred miles from shore. Either by flight or as stowaways in vessels they have pressed eastward to western Kurope and westward to the farthest isles of the Pacific. Well is it named the “ Monarch,” for it is the most daring and indomitable butterfly that we know, pushing back its geographical boundaries to the very edge of the Arctic zone, and exploring on leisurely and confident wing the seas that wash the shores of the Occident and Orient. No wonder the Viceroy chose so splendid a creature to imitate. But I fear there is little noble ambition as a motive to the imitation; just to keep alive as a species is all. The value of such mimicry seems a part and parcel of the Viceroy’s equipment with which to march in the ranks of the fittest. In southern Florida a common butterfly is a species of the bad-tasting family to which the Monarch belongs ; this is a dark mahogany-brown butterfly with no black veins and borders. Therefore, in Florida, our imitative Viceroy doffs his stolen uniform of orange and black and dons another stolen uniform of mahogany-brown. He evidently chooses his liveries for safety and not for their intrinsic beauty; and he is entirely satisfied as long as he successfully masquerades in a guise that shall deceive the keen eyes of the birds of the air. Olden Cities. Fig. 27. Ly THE PERFECT SOCIALISM T is unquestionable that the word “ social- ist” is an epithet of reproach in the popu- lar mind, and is associated with attempts to subvert the law and order of civilized society. Yet the student of history is bound to confess that socialism has been the product of the highest civilization. In every form it has been an attempt, however misguided, to insure the good of society at large through curtailing and regulating the rights of the individual. The underlying idea of socialism has ever been to secure for man upon earth the equal chances for happiness which, it is believed, God in his justice grants to man in the next world. The popular disrepute of socialism is doubtless due, in part, to vari- ous unsuccessful experiments in communal life; but it is due also to the individualism of the human race, which rebels against any levelling tendency. We each prefer to keep our own fighting chance, however poor, to sharing the same with our fellows less fortunate in endowment and environment. 55 56 : WAYS OF THE SIX-FOOTED It is strange that in the history of socialism the fact has been disregarded that, thousands of years before Saint-Simon, Fourier, Owen, and Karl Marx lived and wrote, insects had already solved the problems of prac- tical socialism. Surely, had Solomon been as interested in social experiments as he was in industrial progress he would have said, “Go to the ant, thou socialist, learn her ways of community life and be wise; for she provideth her meat in the summer, and gathereth her food in the harvest, and shareth freely with her fellows the products of her labors.” The successful socialists among insects are bees, ants, and wasps, all of which belong to the order Hymenop- tera. But, as if to show that the lines of social develop- ment in the insect world are founded upon fundamental law, we find another group of insect socialists, the white ants, or termites, which belong to an entirely different order. They differ as much structurally from the ants, bees, and wasps as do men from horses, and yet their social habits are much the same. And even within the Hymenoptera the social habits of bees, wasps, and ants have doubtless been developed independently. Let us examine the claims insects have to be ranked as socialists and see if they are not well founded. The efforts of human socialists have been directed toward non-competitive division of labor, united capital, com- THE PERFECT SOCIALISM 57 munal habitations, and amalgamation of interests. All these conditions and more are to be found in insect societies; for the social insects are uncompromising Malthusians and rigorously control the increase ot popu- lation. We will discuss these claims in detail and see how they are substantiated by the facts observed in the insect world. CASTE Division of labor by caste is a most interesting phase of insect socialism and deserves to be considered first. Our little six-footed brethren have loosed the Gordian knot of division of labor through creating castes more immutable than those of the Brahmins, and they have solved the problems of caste by making their existence a benefit to the whole society instead of to the individuals belonging to the caste. This is brought about by making each caste represent a division of labor based upon the needs of the whole community. The castes are: queens, kings, workers, and soldiers, and a study of the functions of each is necessary in order to understand the economy of the insect commune. Royalty The term “queen” is a misnomer among insects, for they have no rulers in their societies. The queen is 58 WAYS OF THE SIX-FOOTED always the mother of the colony, and the devoted at- tention she receives is due to the fact that without her the community would perish. The queen has reached her highest development in the honey-bee, and we will study her there. From in- fancy she is destined to maternity, and her life-history is briefly as follows: When the workers wish to develop a queen they tear down the partitions between three adjacent cells containing eggs which would naturally develop into workers. They destroy two of the eggs, reserving the third as occupant of the large cell which they proceed to build over it. The egg hatches into a little white bee grub, in no wise differing from those in the neighboring cells. But soon the process of differ- entiation begins, for this grub is fed upon a highly nutritious food, made by the workers, called “royal jelly.” Not for the delectation of the babe in the royal cell is she fed royal jelly, but because this rich diet has a marvellous effect upon her physical development, giving her great capabilities for producing eggs. For five days she is fed upon this stimulating food, and then the work- ers cap her cell and leave her alone to change to a pupa. About sixteen days from the date of hatching, the queen is ready to come out of her cell; the workers know this and are ready to open the cell and help the royal lady out, now in full possession of her legs and THE PERFECT SOCIALISM 59 wings. In appearance she is larger than the largest workers — evidently a queenlier bee. Her first act, if unhindered by the workers, is her one claim to similar- ity to human royalty: she starts at once on a hunt for other queens in the hive, for our queen is jealous and will brook the presence of no other claimant to her throne. Her sting is a noble weapon kept sacred to the slaying of her peers. She hunts for other queen-cells, tears them open with great fury, and assassinates the helpless young princesses within them. But she is quite as ready for fair fight as for assassination, for when she finds another queen fully developed she will fight her until one or the other is killed. The stark bodies of fifteen unfortunate queens we found one day thrown out of one of the hives; grim witnesses to the prowess of the royal lady in possession of the colony. In a few days after maturity the queen takes her marriage flight in the sunshine. As soon as she returns from her honeymoon the queen proceeds at once to business, moving around upon the comb and gluing her eggs to the bottoms of the cells. When the honey season is at its height she works with great rapidity, sometimes laying eges at the rate of six per minute, accomplishing the feat of layimg over three thousand egos per day —nearly twice her own weight. She is a wise queen, moreover, and has an eye to the dangers 60 WAYS OF THE SIX-FOOTED of overpopulation. When there is much honey and great activity on the part of the workers and the swarming season is at hand she enlarges her empire rapidly ; but when there is little honey she takes care that the population be limited to practical numbers. Whether she does this as the result of her wisdom, or whether she is guided by the quality of food the workers give her, is a mooted question. From the point of this discussion it matters not whether it be queen or subjects that evince such foresight ; the fact that interests us is that the bee socialists do control population. The queen also codperates with the workers in de- termining the relative proportions of the two sexes. The workers are developed in comb composed of small cells, the drones in comb composed of larger cells. The greater part of the comb in the brood chamber is of the first type, as it is essential that the greater number of bees reared be workers. But as the swarming season approaches the workers provide comb made up of the larger cells, unless there is already a sufficient quantity in the hive. This constitutes the workers’ part in determining the relative proportion of the sexes in the colony; it remains for the queen to complete the work. In the smaller cells she deposits eggs that will develop into workers, and in the larger cells only those that will develop into drones. THE PERFECT SOCIALISM 61 The queen bee could never accomplish such feats in ege-laying if she were not cared for with great solicitude by the workers. Her powers of motherhood are devel- oped at the expense of the rest of her physique. Her stomach is not fitted for the process of digestion; she is always fed upon digested food, and thus her energies are conserved for her great task. Often in the summer or fall swarms of winged ants may be encountered by the unhappy traveller, who has much to do to keep them out of his eyes and mouth. These winged forms are the king and queen ants taking their marriage flight. As soon as this wedding tour is over they drop to the ground; the kings die soon, the queens tear off their wings in a great hurry, and, like the queen bee, go to work at once. The first eggs the queen ant lays she takes care of herself, housing and feeding the young in a true, motherly way. The first brood is composed of workers, and after their maturity they take care of the nest and the young, and the energies of the queen are reserved for the production of eggs. In one particular is the queen ant more amiable than the queen bee: she suffers no throes of jealousy and dwells in peace with other queens in the nest. The worker ants evidently regulate the size of the royal family. The kings and queens of the termites take flight at 62 WAYS OF THE SIX-FOOTED first as do the ants. The queen and king are adopted into some colony, where they are carefully cared for, a royal cell bemg fashioned for their use. The queen becomes greatly developed in size, until her abdomen is a great ege sac, sometimes six or seven inches long. Of course she cannot move, but lives in imprisoned help- lessness, finding her only relief im the devotion of her consort and subjects. It is a sorry part in the larger affairs of the insect world that is played by the males, whether we call them kings or drones. Much scorn has been heaped upon drones because they are the idlers in the bee com- mune, but surely their lot is the least enviable of all the castes in the hive. The drone’s sole raison d’étre is to be consort of the queen ; but as there are hundreds of drones to one queen, naturally there are very few that fill the office intended for them by nature. Even if one is successful, he loses his life for love; while the many unsuccessful kings without kingdoms are mercilessly sentenced to death by their worker sisters as soon as the honey supply runs low. Cheshire describes the killing of drones thus : — “ No sooner does income fall below expenditure than their nursing sisters turn their executioners, usually by dragging them from the hive, biting at the insertion of the wing. The drones, strong for their special work, Fie. 28, An Ant Town. 64 WAYS OF THE SIX-FOOTED are after all as tender as they are defenceless, and but little exposure and abstinence is required to terminate their being. So thorough is the war of extermination that no age is spared!” The question as to the economy of developing so many useless princes royal is a puzzling one, and can only be explained by the theory that natural selection has acted to preserve those colonies having many drones — another instance of the flagrant waste of individuals for the benefit of the race. I call to mind a slaughter -of drones I once witnessed in an observation hive. The openings in the hive were large enough to admit the workers only and therefore too small to allow the passage of the bodies of the drones; so the determined workers spent several days in tearing their wretched victims limb from limb and removing them in sections. Below a small crevice at the bottom of the hive could be seen a windrow of disjointed legs and wings torn from the poor drones. The king ants die natural deaths, if death from cold and starvation may be called so; at least, they are not subject to assassination as are the king bees. The king termite is a noted ex- ception in the insect world, as he lives a long and exemplary life, sharing with his queen the attention and devotion of his subjects. Devotion to royalty has been much misunderstood by THE PERFECT SOCIALISM 65 the earlier writers. Lubbock and McCook, as well as apiarists, have shown that the devotion to the queen is a matter of business interests to the colony. Not her royal body do they revere but her royal prerogative of motherhood. “What does” is the criterion of social- ists; “what is” counts for nothing. Ants show a great deal of devotion to a dead queen, giving her at- tention for days or even weeks after her death. While the queen bee moves about freely in the hive, the queen ant has a bodyguard which always accompanies her and often restricts her movements. Beekeepers often have occasion to introduce new queens into hives that are queenless. This is a delicate under- taking, and many expedients are resorted to in order to accomplish it successfully. It is interesting to note the manner in which the bees refuse to accept a strange queen. They “ball” her, as it is called; ie. a great number of workers cluster close around her, making a compact ball about the size of an egg, and thus delicately smother her royal highness with much attention. Get- ting rid of unwelcome royalty by the process of smother- ing is not unknown in our own annals. This method is probably adopted by bees through their instinct of never inflicting wounds upon an active queen; it is to be noted that if a queen bee is disabled, she is killed by ordinary methods and pitched out of the hive, thus 66 WAYS OF THE SIX-FOOTED showing conclusively that it is the function of royalty rather than the person that is respected. THe WoRKERS AND CITIZENS The workers constitute by far the greater part of the insect societies; as their name implies, they carry on the industries and business affairs of the community. In the case of ants, bees, and wasps the workers are females whose’ reproductive organs are undeveloped. Among the termites the workers are both male and female, but with similarly rudimentary reproductive systems. Thus it seems that the bearing of young is found incompatible with business life in insect societies. Not so, however, is the care of the young; this is always considered one of the most important of the industries of the commune. Among the bees and ants the care of the young is relegated to the younger sisters, although the elders do not scorn these duties if they find their performance necessary. The first work of the ant or bee just emerged from the pupa state is that of nurse, and a most tender and devoted one she is. Hspecially are the ant nurses solicitous about the health and comfort of their small charges. In some species the young ant grubs are assorted into sizes, those of the same age being kept in the same apartment, suggesting a graded school. When the ant THE PERFECT SOCIALISM 67 babies are hungry they stretch up like young birds, and their nurses regurgitate partly digested food into the gaping, hungry mouths. The nurses keep them very clean by licking them with their long tongues, and, what is more interesting, are very careful to keep them in the right temperature. When the sun shines hot on the nest in the morning the nurses carry their charges to the lower compartments, but toward night they carry them again to the upper nurseries. The nurses show great interest in the young when they emerge from the pupa state, helping them to straighten out their newly freed antenne and legs, then taking a hand at their education by leading them around the city and showing them the ways of the formic world. All the members of the insect commune are shining lights in their devotion to the young. The moment an ant nest is attacked those citizens who are not detailed to fight the imtruders will snatch up the babies and flee with them to places of safety; or when hard pressed will fight to the death for their protection. This is worthy of note, since it is not the mother instinct for saving her young but is a race instinct instead. It may be here stated that the objects popularly known as ants’ eggs are not the eggs, but the young grub ants or pupe; the eggs are too small to be seen well with the naked eye. 68 WAYS OF THE SIX-FOOTED The more successful the insect colony, the greater the number of young. Consider once the labor of the bee nurses, who may have, in strong colonies, twelve thou- sand hungry babies to feed every day. The work of the young bees is truly onerous; for they not only have to be children’s nurses but also have to feed the queen and drones, construct the comb, cap the larve cells, keep the hive clean, and keep it well ventilated by a process of draughts set up by using their wings as fans. To secure the food for the whole society occupies the time of the older and majority of the members of the colony. Among the bees the workers are physically modified for their labors. The hind legs are broadened and concave above, so as to form baskets for the carry- ing of pollen. Between the segments and the lower side of the abdomen are glands for the secretion of wax. Two segments of the hind legs are formed, so as to make forceps to remove the plates of wax after they are secreted. One of the most taxing of the bee industries is the making of wax. Bees gorge themselves with honey, then hang themselves up in festoons, or curtains, to the hive, and remain quiescent for hours; after a time wax scales appear, forced out from the wax pockets. The bees remove these scales with their natural forceps, THE PERFECT SOCIALISM 69 carry the wax to the mouth, and chew it for a time, thus changing it chemically. Thus it may be seen that wax-making is a great expense to the colony, for it costs not only the time of the workers but it is esti- mated that twenty-one pounds of honey is required to make one pound of wax. As a matter of fact much of bee labor is that of the manufacturing chemist. Raw material does not suit their fastidious taste; thus all the honey, their chief food, they take from the nec- taries of flowers as cane sugar, and in the honey stomach mix it with a secretion which changes it into grape sugar. Bees are unwearying workers; they share with the workers of other insect societies an utter recklessness as to their own individual safety and preservation. When a bee goes out for honey she also collects pollen, so that she comes back heavily laden and flying low and slowly. It is no wonder that an ancient Greek writer, noting the pollen upon the legs of a laden bee, states that on Hymettus the bees tie little pebbles to their legs to hold them down. The lavish wastefulness of individual life is shown by the relative longevity of bees during the working and resting season. Those individuals matured in the fall will live eight or nine months, while in the height of the honey season a bee will wear herself out in a month. 70 WAYS OF THE SIX-FOOTED The hours of labor among the ant workers are greater than among bees, as they have been observed working until late at night. Some of the species im hot countries wisely do their labor at night, resting in their nests during the heat of the day. There seems to be more originality and variety to the labors of ant workers than we find among bee workers. The foragers bring back a great variety of food for the house- keepers and the young. Certain species in dry coun- tries provision their nests for the winter. The ants perform Herculean labors while excavating their tunnels as well as when carrying great burdens of food. The worker ants have a delightful habit of taking naps when they are tired. McCook describes their sleepmg positions thus : — “Some are squatted down on their abdomens and last two pairs of legs; some le upon their sides ; some are resting upon the hind legs, standing on tip-toe; some are crouched upon the earth with faces downward ; several are piled one on top of another.’ When they awaken they stretch and yawn in the most naive and human manner. In an ant’s nest one thing is most noticeable ; however crowded the galleries may be, and however much the ants may be obliged to crawl over and push each other, they do it with the utmost good nature. Another noticeable thing is the free way in THE PERFECT SOCIALISM 71 which the foragers feed the hungry. An individual seldom asks in vain for food. In spite of the thriftiness, the instinct of sharing is stronger than the instinct of accumulation. The generosity of these insect citizens toward each other is an ideal which still lies beyond the horizon of accomplishment in the human world. The termite workers are of both sexes, and their industry is such that they prove a terrible plague in the tropical countries, where they abound. Our native species tunnel their nests in wood, and are, in fact, very skilful engineers, for they build covered ways, under which they work. A feat not only of engineering skill but skill in reasonmg came to our eyes in our own insectary.
